The Toyota Mirai is a four-door, mid-size sedan with a twist—it uses no gasoline and emits nothing but water vapor. The groundbreaking fuel-cell electric vehicle is powered by hydrogen, re-fuels in about five minutes and travels up to 300 miles on a full tank.

Toyota has just announced that it is making available thousands of hydrogen fuel-cell patents—royalty free. In fact, Toyota will grant royalty-free use of approximately 5,680 fuel-cell-related patents held globally, including critical technologies developed for the new Toyota Mirai. The list includes approximately 1,970 patents related to fuel-cell stacks, 290 associated with high-pressure hydrogen tanks, 3,350 related to fuel-cell system software control and 70 patents related to hydrogen production and supply.
